9 Claims.

This invention relates to a carriage or truck for unreeling a Fourdrinier wire bundle into an open loop in the aisle adjacent a Fourdrinier paper making machine and more specifically relates to a wheeled carriage having clamp members rotatable about a fixed axis for receiving the ends of the spool poles of a Fourdrinier wire bundle to facilitate the unreeling of the bundle into an open loop.

This application is a division of our copending application entitled: Fourdrinier wire stringing device and method, Serial No. 183,629, filed January 6, 1938.

Fourdrinier wires, for paper making machines, are conventionally shipped in bundles formed by inserting a pole within the loop of the wire and by wrapping the wire double around another pole outside of the loop and the inserted inside pole. The free end of the wire then receives another pole within the loop thereof.

The first pole will hereinafter be called the "inside wire spool pole while the other pole around which the wire is wrapped will be identified as the outside wire spool pole. The pole inserted through the free end of the wire will be referred to as the inside wire free end pole.

The carriage, trolley or truck of this invention has revolvable clamps thereon for receiving the spool poles of a Fourdrinier wire bundle. The carriage also has overhead supports for receiving the ends of the free, end pole of the Fourdrinier bundle. Receptacles are provided on the. carriage for receiving additional intermediate poles inserted in the loop of the wire mounted on the carriage between the spool poles and the free end pole.

In unreeling the wire bundle from the carriage to form an open loop of the Fourdrinier wire in the aisle alongside of a paper making machine, the free end pole of the wire bundle is transferred from the overhead carriage supports to brackets on the upper ends of a pair of posts mounted in the aisle adjacent the breast roll end of the machine. One of the intermediate poles on the carriage within the loop of the wire is then transferred to brackets carried at the the revolvable clamps of the carriage to meal the wire. Other intermediate poles on the carriage within the loop of the wire are then transferred to overhead supports at spaced intervals above the aisle for supporting the upper run of the wire loop. The carriage may also carry additional poles outside of the loop of the wire for placing on the aisle floor to support the lower run of the loop.

When the carriage reaches the couch roll en of the machine, the inside wire pole of the spool poles is transferred from the revolvable clamps on the carriage to the upper brackets of another pair of posts mounted in the aisle. An intermediate pole on the carriage within the loop of the wire is next transferred to lower brackets on the same posts. The wire is thus disposed in an open loop in the aisle adjacent the table structure of the machine.

The table structure of the paper machine can then be laterally removed into the open loop of the wire according to known methods such as, for example, on laterally extensible rails as disclosed in the Earl E. Berry Patent No. 2,003,103 dated May 28, 1935.

It is, then, an object of this invention to provide a carriage for unreeling a Fourdrinier wire bundle into an open wire loop adapted to receive the removable table structure of a paper making machine therein.

A further object of the invention is to provide a carriage for facilitating the stringing of a the following detailed description of the annexed sheets of drawings which disclose a preferred embodiment of the invention.

On the drawings:

Figure 1 is an end elevational view of a Fourdrinier wire bundle as it is wrapped by the manufacturer.

Figure'2 is a side elevational view of a carriage, trolley or truck according to this invention for unreeling the wire bundle into an open loop.

taken along the line IV-IV of Figure 3.

Figure 5 is a fragmentary diagrammatic side elevational view illustrating the manner in which the carriage of this invention is utilized to un-- reel a Fourdrinier wire bundle into an open loop.

As shown on the drawings:

In Figure 1 the reference numeral I designates generally a Fourdrinier wire bundle as the same is shipped by the wire manufacturers. The bundle |0 comprises an inside wire pole B disposed in one end .of the endless Fourdrinier wire F.W. The wire is then wrapped around the inside wire pole B and an outside wire pole C. The other end of the endless wire receives the inside wire pole A therethrough. Since the poles A and B are the only poles inside the loop ofthe wire they are called inside wire poles. The poles B and C, however, form the spool around which the wire bundle I0 is formed and a pole A merely protects the free end of the wire.

As shown in Figures 2 and 3 the reference numeral designates generally a carriage or trolley for unreeling the wire bundle [0 into an open loop adapted to receive the table structure of a paper making machine therein.

The carriage consists of side frame members |2 joined together by transverse tubes l3. The tubes |3 are held in the frame members |2 by means of bolts such as [4.

The shanks |5 of casters |6 are swivelly mounted through the ends of the tubes I3 in each frame member l2, thereby providing four swivelly mounted casterwheels |6 for the car.- riage.

The casters |6 have gears secured around the shanks thereof meshing with worms secured on shafts l8 mounted under each frame l2 in brackets l9 and 20. Cranks 2| are secured on the front ends of the shafts |8 for manual rotation of the shafts to turn the casters and thus steer a the carriage.

The frames |'2 have upwardly extending pedestal portions 22 at the front end of the carriage. Bearing housings 23 are bolted on top of the pedestals 22 and the shafts 24 of clamp members 25 are rotatively mounted on bearings (not shown) in the bearing housings 23.

The ends of the clamp members 25 are grooved as at 26 (Fig. 3) for receiving therein the shanks of bolts 21 pivotally mounted on the ends of yoke members 28 cooperating with the clamp members 25. Nuts 21a can be threaded on the ends of the bolts 2'! for drawing the yokes 28 towards the members 25.

The members 25 and 28 are thus revolvable in the bearing housings 23.

As best shown in Figures 3 and 4, the bearing 7 housings 23 are each provided with an inwardly extending lip 23a for supporting a brake band such as 30 disposed around each shaft 24 of a member 25.

As shown in Figure 4 one end of the brake band 30 is secured to a bracket 3| extending through the lip 23a and held in fixed position thereon by means of nuts 32 engaging the opposite faces of the lip.

The other end of the brake band 30 is secured to a bracket 33 having a threaded shank portion 34 extending through the lip 23a and receiving in threaded relation thereon a thumb nut 35 adapted to abut the top face of the lip 23a. Manipulation of the nut 35 thus controls the frictional engagement between the brake band 30 and the shaft 24.

As shown in Figure 3, a brake 38 is provided for each shaft 24.

tal position for receiving the wire poles by tight-' ening the brake bands 30. The yoke members 28 are then secured on the members 25 to clamp the spool poles in position. I

When the bundle ID has thus been assembled on the carriage II, the free end pole A may be moved down to supports such as 36 formed on the frame members |2 behind the pedestals 22.

Vertical posts 31 and 38 are mountedon the frames l2 in spaced relation from the back end of the carriage. Pole receiving brackets 39 are secured at the tops of the posts 31 and 38.

A bracket 40 is clamped on the post 31 in spaced relation from the top thereof. The bracket 48 has an inwardly and downwardly extending arm portion 4| and an outwardly and upwardly extending arm portion 42 as best shown in'Figure 3. Concave guide rollers 43 and 44 are rotatively carried on the ends of the arms 4| and 42 respectively around axlepins 45 projecting horizontally from the arms toward the rear of the carriage. The arrangement of the arms is such to mount the rollers for receiving a pole therebetween and for holding the pole trans- .versely across the carriage in a cantilevered position. However, the free end of the pole can be tilted upward for a purpose to be hereinafter more fully described.

Pins or posts such as 46 are mounted on the frames |2 in spaced parallel relation behind the posts 31 and 38 to define with the posts 31 and 38 a pole receptacle 41.

A second set of pins or posts 48 are mounted on the back ends of the frames |2 to define with the posts 46 a second pole receptacle 49.

Brackets such as 58 are mounted under the frames |2 for supporting wire poles for a purpose to be hereinafter described.

A tray 5| is mounted on the front tube H1 in the central portion of the carriage. The tray 5| supports wire pole blocks 52 for a purpose to be hereinafter described.

In charging the carriage for unreeling a Fourdrinier wire bundle into an open loop, the wire bundle is mounted on the clamps 25 as explained above. Wire pole A is then moved from the support 36 to the brackets 39 at the top of the posts 31 and 38. During this positioning of the wire pole A, the wire F. W. is unreeled from the spool poles B and C to form an open loop between the clamps 25 and the pole A as best shown in Figure 2. Wire poles D, E and F are then inserted through the loop of the wire in the receptacle 49 provided on the carriage. Additional wire pole s G, H and J are also inserted through the loop of the wire and seated in the receptacle 41 of the carriage.

Outside wire poles K, L and M are mounted on the brackets 50 of the carriage and the pole blocks 52 are placed in the tray 5|.

The carriage is then charged for unreeling the Fourdrinier wire into an open loop adjacent the table structure of a Fourdrinier paper making machine.

As shown in Figure 5, an aisle floor 60 alongside of a paper making machine (not shown) has vertical posts such as 66 mounted thereon adjacent the breast roll end of a paper making machine. The posts 66 are spaced apart from each other for a suflicient distance to receive the carriage II therebetween.

The posts 66 have lower pole-receiving brackets 61 near the bottoms thereof and upper polereceiving brackets 68 at the tops thereof. The brackets 61 and 68 face the couch roll end of the machine.

With the carriage ll charged as shown in Flgures 2 and '7, the same is moved along the aisle 60 between the posts 66. The wire pole A is then transferred from the bracket 39 on the carriage posts 31 and 38 into the brackets 68 on the aisle posts 66.

The intermediate pole D, which is the top pole in the receptacle 49 of the carriage, is then transferred from the receptacle into thebracket 61 of the aisle posts 66. The carriage is then moved along the aisle while unreeling the forming wire F. W. from the spool poles B and C by rotation of the clamps 25.

The next roll E in the receptacle 49 of the carriage is removed from the receptacle and suspended between the rollers 43 and 45 on the carriage post 3'! to hold the pole in a cantilever position. The free end of the pole is then tilted upwardly to engage a cable 10 suspended from the ceiling (not shown). The other end of the pole is then removed from the rollers 43 and 45 and mounted in a complementary cable to suspend the pole horizontally from the ceiling and hold the upper run of the wire F. W. in a substantially horizontal position level with the bracket 68 on the posts 66. i

A pair of pole blocks 52 are then removed from the tray on the carriage and are mounted on the aisle floor. The pole K is then removed from the brackets 50 on the carriage and mounted on the pole blocks 52 to hold the lower run of the wire F, W. above the aisle floor.

In a similar manner the intermediate poles F and G are removed from the carriage and suspended from overhead cables to hold up the upper run of the wire F. W. Likewise, the poles L and M are removed from the carriage and mounted on pole blocks on the aisle floor under the under run of the wire to hold the'wire above the floor.

An additional pair of posts such as 66 are mounted on the aisle floor at the couch roll end of the machine and the remaining poles H and J on the carriage can be mounted in double lower post brackets (not shown) on the posts. The inside Wire spool pole B is transferred from the clamps 25 of the carriage to the upper bracket of the posts and the outside wire spool poles D can be transferred to the supports 36 of the carriage.

The wire F. W. is thus disposed in an open loop in the aisle 60 adjacent the removable table structure of a Fourdrinier paper making machine. The upper run of the loop can be raised as shown in dotted lines in Figure 5 by shortening the cables and the removable table structure of the machine can be readily moved into the open loop for receiving the wire therearound.

From the above description it should be understood that this invention provides for the unreeling of a Fourdrinier wire from a bundle into an open loop in the aisle alongside of a paper making machine. The table structure of the paper making machine can then be moved into the open loop of the wire.

The carriage of this invention provides for the replacing of a new Fourdrinier wire on Fourdrinier paper making machines having removable table structures without damaging the wire and without requiring skilled technicians to effect the wire change.

It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
